Study on Energy Efficiency Evaluation Model of 110 kV Universal Design Substation

摘要: 经济的飞速发展离不开电力，而大量变电站的投运所带来的能源消耗问题越来越受到重视，评估变电站的运行管理的能效，从而提高变电站能效水平，对于实现绿色环保变电站的建设意义重大。本文通过对内蒙古东部地区现有的110 kV通用设计变电站的实地调查和测量统计，研究变电站的运行管理方法和电力设备的用能特点，采集反应变电站能耗的相关数据，提出能效评估的指标体系，结合国家行业标准，确定基于层次分析法的各因子在变电站能效中的权重，最后利用模糊评判法对110 kV通用设计变电站能效进行综合评定，从而得到完整的能效评估体系。利用实际测量的变电站能效数据对模型进行验证，证明了其可行性，为110 kV通用设计变电站的能效优化提供了指导。

Abstract: The rapid development of economy is inseparable from the power, and the energy consumption brought by the operation of a large number of substations attracts more and more attention. It is of great significance to evaluate the energy efficiency of substation operation and management so as to improve the energy efficiency of substations. Based on the investigation and measurement of 110 kV universal design substation in the east of Inner Mongolia, this paper studies the operation and management methods of substation and the energy consumption characteristics of the power equipment, collects the data which reflects energy consumption of the substation and puts forward the energy efficiency evaluation index system. Finally, the energy efficiency of 110 kV universal design substation is evaluated synthetically by fuzzy judgment method, and then a complete energy efficiency evaluation system is obtained by combining the national industry standard and the weight of each factor based on AHP in the energy efficiency of the substation. The feasibility of the model is proved by the actual measured energy efficiency data of the substation, which provides the guidance for the energy efficiency optimization of the 110 kV universal design substation.
